Ampulla of Vater Cancer in a Patient with Double Common Bile Duct

ABSTRACT

Of the various anomalies of the biliary system, a double common bile duct (DCBD) is extremely rare. According to a report by Boyden, the first case of DCBD was reported by Vesalius in 1543, with few additional case reports since 1986. Cancer and Anomalous pancreatobiliary ductal union (APBDU) are the two of the most serious concomitant conditions. A 69-year-old female was admitted to our hospital with the complaint of jaundice. An abdominal computed tomography and percutaneous transhepatic cholangiography revealed a mass lesion at the distal common bile duct. The patient underwent Whipple's operation, and the operative finding showed a septum in the common bile duct, with a DCBD opening as a single duct into the ampulla of Vater. A histological examination showed an adenocarcinoma in the ampulla of Vater. Herein, a case of the ampulla of Vater cancer in a patient with a double common bile duct is reported, with a review of the literature.
